10.5 Survival.  Termination of this Agreement shall not relieve the Parties of any obligation accruing prior to such termination, nor affect in any way the survival of any other right, duty or obligation of the Parties which is expressly stated elsewhere in this Agreement to survive such termination.  Without limiting the foregoing and except as expressly set forth otherwise in this Agreement, Section 1, Section 5 (solely to the extent any payments became payable prior to the effective date of such expiration or termination), Section 6 (with respect to Sections 6.1, 6.2, and 6.3, solely to the extent any payments became payable prior to the effective date of such expiration or termination), Section 7, Section 8, Section 9, Section 10.5, Section 12, and Section 13 shall survive to the extent applicable.  Except as otherwise expressly provided herein, all other rights and obligations of the Parties under this Agreement shall terminate upon termination of this Agreement.  For clarity, the Parties acknowledge and agree that the license grants in Section 2.1 are intended to be perpetual and irrevocable, subject to Sections 10.3 and 10.4.
10.6 Bankruptcy Code.  If this Agreement is rejected by a Party as a debtor under Section 365 of the United States Bankruptcy Code or similar provision in the bankruptcy laws of another jurisdiction (the “Code”), then, notwithstanding anything else in this Agreement to the contrary, all licenses and rights to licenses granted under or pursuant to this Agreement by the Party in bankruptcy to the other Party are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the Code (or similar provision in the bankruptcy laws of the jurisdiction), licenses of rights to “intellectual property” as defined under Section 101(35A) of the Code (or similar provision in the bankruptcy laws of another applicable jurisdiction).  The Parties agree that a Party that is a licensee of rights under this Agreement shall retain and may fully exercise all of its rights and elections under the Code, and that upon commencement of a bankruptcy proceeding by or against a Party under the Code, the other Party shall be entitled to a complete duplicate of, or complete access to (as such other Party deems appropriate), any such intellectual property and all embodiments of such intellectual property, if not already in such other Party’s possession, shall be promptly delivered to such other Party: (a) upon any such commencement of a bankruptcy proceeding upon written request therefor by such other Party, unless the bankrupt Party elects to continue to perform all of its obligations under this Agreement; or (b) if not delivered under the foregoing subclause (a), upon the rejection of this Agreement by or on behalf of the bankrupt Party upon written request therefor by the other Party.  The foregoing provisions of this Section 10.6 are without prejudice to any rights a Party may have arising under the Code.

13.2 Severability.  Should one or more of the provisions of this Agreement become void or unenforceable as a matter of Applicable Laws, then this Agreement shall be construed as if such provision were not contained herein and the remainder of this Agreement shall be in full force and effect, and the Parties will use their best efforts to substitute for the invalid or unenforceable provision a valid and enforceable provision which conforms as nearly as possible with the original intent of the Parties.
13.3 Governing Law; English Language.

Alnylam and Dicerna Form RNAi Therapeutics Collaboration on Alpha-1 Antitrypsin Deficiency-Associated Liver Disease and Complete Cross-License Agreement for Primary Hyperoxaluria Programs


- Dicerna to Lead Global Clinical Development and U.S. Commercialization of its DCR-A1AT and Alnylam’s ALN-AAT02 Investigational Therapeutics for the Treatment of Alpha-1 Liver Disease; Alnylam Retains Post-Phase 3 Opt-in Right for Ex-U.S. Commercialization -  
- Companies Complete Non-Exclusive Intellectual Property Cross-License Agreement for the Development and Commercialization of Alnylam’s Lumasiran and Dicerna’s Nedosiran Investigational Programs for Primary Hyperoxaluria -  










CAMBRIDGE, Mass. and LEXINGTON, Mass. --[BUSINESS WIRE]--April 6, 2020 - Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), and Dicerna Pharmaceuticals, Inc. (Nasdaq: DRNA), both leaders in the field of ribonucleic acid interference (RNAi) therapeutics, announced today the formation of a development and commercialization collaboration on investigational RNAi therapeutics for the treatment of alpha-1 antitrypsin (A1AT) deficiency-associated liver disease (alpha-1 liver disease). In addition, the companies have completed a cross-license of their respective intellectual property for Alnylam’s lumasiran and Dicerna’s nedosiran investigational programs for the treatment of primary hyperoxaluria (PH). These agreements will enhance and accelerate Alnylam’s and Dicerna’s ability to bring these orphan product candidates to market.  
“We are excited to bring our two leading RNAi therapeutics companies together in our efforts to advance potentially transformative medicines for the treatment of two rare diseases with significant unmet medical need. Specifically, the new agreements allow for Alnylam and Dicerna to join forces in areas of common interest, namely alpha-1 liver disease and primary hyperoxaluria,” said John Maraganore, Ph.D., Chief Executive Officer of Alnylam. “We look forward to collaborating with Dicerna to advance treatments for patients living with alpha-1 liver disease, where Dicerna will lead development and U.S. commercialization while Alnylam retains an ex-U.S. commercialization option, where the company already has the resources and experience to hit the ground running. Moreover, our cross-license agreement for primary hyperoxaluria puts the needs of patients and the patient community first, and ensures freedom to operate for both companies for their respective RNAi therapeutic programs in this ultra-rare orphan disease.”
“These agreements between Alnylam and Dicerna represent biopharma collaboration at its best, unifying the strengths of two leaders in RNAi innovation to rally behind the common goal of delivering much-needed new therapies to patients with rare diseases,” said Douglas M. Fambrough, Ph.D., President and Chief Executive Officer of Dicerna. “By joining our efforts in alpha-1 liver disease, we believe we can be more strongly assured of bringing forward the therapy with the greatest potential to benefit patients. At the same time, our agreement related to lumasiran and nedosiran clears a path for each company to offer a new and differentiated treatment to patients with PH.” 
Under the development and commercialization agreement, Alnylam’s ALN-AAT02 and Dicerna’s DCR-A1AT, investigational RNAi therapeutics, each in Phase 1/2 development, will be explored for the treatment of alpha-1 liver disease. Under the agreement, Dicerna assumes responsibility for both ALN-AAT02 and DCR-A1AT at its cost, and may progress one or both of these investigational medicines through clinical development. Dicerna will select which product candidate(s) to advance in development for the treatment of patients with alpha-1 liver disease. At the completion of Phase 3, Alnylam has the no-cost opportunity to opt-in to commercialize the selected candidate in countries outside the U.S., where it already has a commercialization infrastructure in place. If Alnylam exercises its opt-in right, each party shall pay tiered royalties to the other party based on net product sales generated in its territory at rates dependent on which candidate is commercialized. In the event Alnylam waives its commercialization option, Dicerna 








will retain worldwide rights to commercialize the selected candidate(s) in exchange for milestones and royalties payable to Alnylam, also at a rate dependent on which candidate is ultimately commercialized.
In a separate agreement, Alnylam and Dicerna granted each other a non-exclusive cross-license to their respective intellectual property related to their PH treatment investigational programs to ensure that each party has the freedom to develop and commercialize its respective product candidate: Alnylam’s lumasiran targeting glycolate oxidase (GO) for the treatment of PH type 1 and Dicerna’s nedosiran targeting lactate dehydrogenase A (LDHA) for the treatment of PH types 1, 2, and 3. Alnylam’s lumasiran has achieved positive Phase 3 results in the ILLUMINATE-A study and is currently the subject of a rolling new drug application (NDA) with the U.S. Food and Drug Administration (FDA). Dicerna’s nedosiran is currently being evaluated in the PHYOXTM clinical development program in patients with PH. The cross-license agreement provides for Alnylam to pay mid- to high-single-digit royalties to Dicerna based on global net sales of lumasiran and for Dicerna to pay low-single-digit royalties to Alnylam on global net sales of nedosiran.
The transaction related to alpha-1 liver disease is subject to the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and other customary conditions.




About ALN-AAT02 and DCR-A1AT
ALN-AAT02 and DCR-A1AT are investigational, subcutaneously administered RNAi therapeutics targeting alpha-1 antitrypsin (A1AT) in development for the treatment of A1AT deficiency-associated liver disease (alpha-1 liver disease). ALN-AAT02 utilizes Alnylam's enhanced stabilization chemistry plus (ESC+)-GalNAc-conjugate technology, which enables subcutaneous dosing with increased selectivity and a wide therapeutic index. DCR-A1AT utilizes Dicerna’s GalXCTM technology, which enables subcutaneous delivery and optimizes the activity of the RNAi pathway so that it operates in the most specific and potent fashion. The safety and efficacy of ALN-AAT02 and DCR-A1AT have not been evaluated by the FDA, EMA or any other health authority.




About Alpha-1 Antitrypsin Deficiency-Associated Liver Disease
Alpha-1 antitrypsin (A1AT) deficiency is an autosomal disorder that results in disease of the lungs and liver. A1AT is a liver-produced serine proteinase inhibitor with the primary function of protecting the lungs from neutrophil elastase and other irritants that cause inflammation. About 95 percent of people with A1AT deficiency are homozygous and carry two copies of the abnormal Z allele (PiZZ) which expresses the Z-AAT protein. In the liver, misfolding of the mutant Z-AAT protein hinders its normal release into the blood thereby causing it to aggregate in hepatocytes, leading to liver injury, fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). There are estimated to be approximately 120,000 individuals with the PiZZ mutation in the U.S. and major European countries, and of these, 10 percent or more have an associated liver 








pathology (alpha-1 liver disease) caused by the aggregates of the misfolded Z-AAT protein. The only treatment options presently available for alpha-1 liver disease patients are supportive care and, in the case of advanced cirrhosis, liver transplantation. RNAi-mediated inhibition of A1AT in people with alpha-1 liver disease may represent a promising new way to treat this rare disease.




About Lumasiran
Lumasiran is an investigational, subcutaneously administered RNAi therapeutic targeting glycolate oxidase (GO), in development for the treatment of primary hyperoxaluria type 1 (PH1), an ultra-rare life threatening disease. GO is encoded by the hydroxyacid oxidase 1 (HAO1) gene. Thus, by silencing HAO1 and depleting the GO enzyme, lumasiran inhibits production of oxalate – the metabolite that directly contributes to the pathophysiology of PH1. Lumasiran utilizes Alnylam's Enhanced Stabilization Chemistry (ESC)-GalNAc-conjugate technology, which enables quarterly subcutaneous maintainence dosing with increased potency and durability and a wide therapeutic index. Lumasiran has received both U.S. and EU Orphan Drug Designations, a Breakthrough Therapy Designation and pediatric rare disease designation from the U.S. Food and Drug Administration (FDA), and a Priority Medicines (PRIME) designation from the European Medicines Agency (EMA). The safety and efficacy of lumasiran have not been evaluated by the FDA, EMA or any other health authority.




About Nedosiran
Nedosiran (formerly referred to as DCR-PHXC) is the only RNAi drug candidate in development for primary hyperoxaluria (PH) types 1, 2 and 3 and is Dicerna’s most advanced product candidate utilizing the proprietary GalXCTM RNAi technology platform. Nedosiran is designed to inhibit the lactate dehydrogenase A (LDHA) enzyme – an enzyme that catalyzes the final step in a common pathway resulting in oxalate overproduction in patients with PH1, PH2 and PH3. Dicerna is evaluating the safety and efficacy of nedosiran in patients with all known forms of PH as part of its PHYOX clinical development program.




About Primary Hyperoxaluria (PH) 
PH is an ultra-rare disease with three known types (PH1, PH2 and PH3), each resulting from a mutation in one of three different genes. In patients with PH, excessive oxalate production results in the deposition of calcium oxalate crystals in the kidneys and urinary tract and can lead to the formation of painful and recurrent kidney stones and nephrocalcinosis. Renal damage is caused by a combination of tubular toxicity from oxalate, calcium oxalate deposition in the kidneys, and urinary obstruction by calcium oxalate stones. Compromised kidney function exacerbates the disease as the excess oxalate can no longer be effectively excreted, resulting in subsequent accumulation and crystallization in bones, eyes, skin, and heart, especially in patients with PH1 and PH2, leading to severe illness and death. Current treatment options are very limited and include frequent renal dialysis or combined organ transplantation of liver and kidney, a procedure with high morbidity that is limited due to organ availability. Although a minority of patients are fully responsive to Vitamin B6 therapy, there are no approved pharmaceutical therapies for PH.












About RNAi 
RNAi (RNA interference) is a natural cellular process of gene silencing that represents one of the most promising and rapidly advancing frontiers in biology and drug development today. Its discovery has been heralded as “a major scientific breakthrough that happens once every decade or so,” and was recognized with the award of the 2006 Nobel Prize for Physiology or Medicine. By harnessing the natural biological process of RNAi occurring in our cells, a new class of medicines, known as RNAi therapeutics, is now a reality. Small interfering RNA (siRNA), the molecules that mediate RNAi and comprise Alnylam’s and Dicerna’s RNAi therapeutic platforms, function upstream of today’s medicines by potently silencing messenger RNA (mRNA) – the genetic precursors – that encode for disease-causing proteins, thus preventing them from being made. This is a revolutionary approach with the potential to transform the care of patients with genetic and other diseases.
